"The most admirable inventions would never have been known if common sense had not helped them to be produced, strengthening those who conceived them by the support of logic, which demonstrated to them the truth of their presumptions. "Authority follows, based on the experience which, by maintaining the effect of judgment, has armed them with the strength of the mind, the true glory of peaceful conquerors." Would one not say that the Shogun, in writing these lines, foresaw the magnificent efforts which we are witnessing each day and that from the depths of time he caught a glimpse of these brave conquerors of the air and of space, whose great deeds, seeming at times the result of a crazy temerity, are in reality only homage rendered to common sense, which has permitted them to calculate the value of their initiative without mistake? And one can not be denied the pleasure of entering once more into close communion of thought with the old philosopher when he says: "Enthusiasm is of crystal but common sense is of brass."
